Yea, I didn't know until recently that Mormons are a big % of Boy Scout membership. I guess a big part of the drop is probably them after they started letting in girls.
2018 -- "The Mormon Church has been the largest participant of the Boy Scouts in the United States, making up nearly 20 percent of all of the Boy Scouts’ 2.3 million youth members." https://www.washingtonpost.com/news/morning-mix/wp/2018/05/09/mormon-church-breaks-all-ties-with-boy-scouts-ending-100-year-relationship/
